Set brand as origin if brand is empty

[wpscholar]

Is your feature request related to a problem? Please describe.

Currently, we set a $container->get('plugin')->id, which gets passed as origin to the Hiive. We also send a brand property to the Hiive, which is the value of the mm_brand (soon to be nfd_brand) option. As such, we are getting a lot of empty brand values.

Describe the solution you'd like

We need to make sure we set the passed brand as either not empty, or we need to update the empty brand property to match the origin (plugin ID).
